ICAR Technical Series no. 7 - Nitra Proc.

Luger et al.There is no difference between device 1 and device 3, but a significantdifference to all the others. Further more there is a significant differencebetween device 4 and device 5. Between device 2 and device 5 no significantdifferences could be observed.Although high significant differences between the both vacuum levels(P < 0.001) could be observed (Table 3).Table 3.
